Inflammatory mediators in respiratory tract

Inflammatory mediators in the respiratory tract refer to a large and heterogeneous group of soluble molecules—including cytokines, chemokines, eicosanoids, histamine, and proteases—that regulate immune and inflammatory processes in pulmonary tissue. Key pro-inflammatory cytokines include interleukin-1β (IL-1β), IL-6, IL-8 (CXCL8), tumor necrosis factor alpha (TNF-α), interferon gamma (IFN-γ), IL-4, IL-5, and IL-13; anti-inflammatory mediators include IL-10 and TGF-β. These molecules are released from various cells (e.g., epithelial cells, macrophages, dendritic cells, lymphocytes, mast cells) in response to pathogens, allergens, pollutants, or injury, and orchestrate leukocyte recruitment, vascular changes, tissue remodeling, and the perpetuation or resolution of inflammation. Dysregulation and persistent production of these mediators is implicated in the pathogenesis of diseases such as asthma, COPD, ARDS, and respiratory infections. While some mediators (e.g., IL-5, IL-4, IL-13, TNF-α) serve as validated therapeutic targets in asthma and allergic diseases, "inflammatory mediators in respiratory tract" as a collective is not itself a canonical drug target but a class of related molecules with overlapping and sometimes opposing functions. This term is too broad and non-specific for use as a single drug target entry. For structured pharmacological information, refer to specific mediators such as "Interleukin-5", "Tumor necrosis factor alpha", or "Interleukin-6".
